Bat for Lashes, 'Two Suns' (Astralwerks)

Is sultry English multi-instrumentalist Natasha Khan more than just the latest Sarah McLachlan for indie snobs? Her mezzo-soprano is so damn beautiful that it initially upstages all else on her second album, and her cosmic love poetry blurs into abstraction without a lyric sheet. But after repeated plays, you become mesmerized by the loopy details: Conjuring ancient tribal vibes from ominous synths and galloping tom-toms, this art-rock Joan of Arc gushes duality motifs that thwart narrative but overflow with moonstruck sensuality. Two Suns is the rare concept album that's better for the bedroom than for bong hits.
